Welcome Intercity Alarm Customers

Our local monitoring station has been protecting Massachusetts residents since 1972


For more than 45 years, we've been protecting individuals, families, and businesses here in New England.

We are dedicated to providing Intercity Alarm customers with the latest in security innovation and technology and the highest standards of customer service in the region.

September 1972

Founder Douglas M. Curtiss founds Sonitrol Security Systems of Hartford, a commercial security company based out of Rocky Hill, CT.

We later merge with other local Sonitrol companies to become Sonitrol New England.


1970s - 1980s

Working closely with local police and fire departments, we make huge improvements aimed at reducing false alarms.

The authorities trust our alarm systems and verification process; that's why when one of our alarms get off, emergency response times are significantly faster compared to many competitors.


1980s - 1990s

Business owners and longtime customers start asking us if they can put Sonitrol systems in their homes as well.

We expand our alarm systems and monitoring services across the state. Now, we're protecting homeowners, school districts, and small businesses, too.


1990s - 2000s

We expand into other states in New England, acquiring residential alarm companies in Rhode Island (HB Alarm) and Massachusetts (Intercity Alarms).

Our residential security team is later rebranded as Alarm New England.



The Alarm New England team continues to add more offices around Massachusetts, setting up a team in the heart of downtown Boston.

This transition marks our shift towards professional-grade DIY home security systems, smart home automation, flexible installation options, and an end-to-end user experience that people trust.



Alarm New England continues to expand its range of products and services to make our communities safer places to live. We now protect over 27,000 of our fellow New England residents in Massachusetts, Connecticut, and Rhode Island.

Protection you can count on.

Sometimes, the simplest facts speak the loudest.

Our customers speak for us.

Generations of developing security expertise, building partnerships with the authorities, and listening to customer feedback have helped us find new ways to protect the local community.

You can feel confident that, with over four decades of experience,  Alarm New England will provide you with the highest level of protection and service.

Feel free to give us a call if you have any questions.

"Connie and I set up my Alarm New England system yesterday over the phone. It couldn't have been any easier. As a small business owner and also female, I feel safe and super pleased with myself for being able to set everything up on my own!"

“This has to be one of the best experiences I have ever had with a utility or vendor. The customer service is very knowledgeable and friendly, best of all, it’s not outsourced overseas and you can understand and appreciate your IT person. Thanks again Alarm New England.”

“I had ADT out and they wanted an astonishing amount of money upfront, then run wires through my whole house, it was terrible. Alarm New England sent me a box of wireless home security equipment and had Connie, their Head of Tech FaceTime me to help me set it up for free!”
